WASHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 461,125, dated October13, 1891. Application filed May 25,1891- Serial No. 393,934- (No model.)

To all whom it may concern:

Be it known that I, JACOB BORST, of Brooklyn, in the county of Kings andState of New York, have invented a new and useful Improvement inApparatus for \Vashing Filtering Material, of which the followingis aspecification.

My invention relates to an improvement in apparatus for washingfiltering material, and more particularly for washing filtering materialemployed in connection with the manufacture of malt liquors.

The particular filtering material which it is found advantageous to usein filtering beer is of such a nature that it is liable to dissolve ifsubmitted to water at too high a temperature and is liable to suliermaterial waste if submitted to a stirring or a chafing action. On theother hand, it is desirable that the pure water employed as a cleansingagent' should be used as hot as possible without danger of dissolvingand wasting the filtering material, and it is also desirable that thematerial should be thoroughly rinsed and cleansed.

The object of my present invention is to provide means for submittingthe filtering material to the water as hot as may be used without dangerof injury and waste of the filtering material and at the same timeprovide for squeezing and thoroughly rinsing the material withoutstirring o r seriously chafing it.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure l is a view through the tub andwasher transverse to the axis upon which the washer vibrates. Fig. 2 isa vertical section through the tub, washer, and supply-tank on the line0c :r, Fig. 1, one pair of yielding arms being removed, in a directionlengthwise of the axis upon which the washer vibrates; and Fig. 3 is aview in detail showing in transverse section a portion of the woven-wirefabric which forms the bottom or curved floor of the washer.

The supply-tank is represented by A, and the tub by B. In the presentinstance I have shown the tub as located within and forming asubdivision of the supply-tank A. \Vater is admitted from thesupply-tank into the in vertical section tub through a perforated pipe12, leading from the bottom of the supply-tank along the bottom of thetub and provided with openings throughout its length to admit the waterinto the tub. The said supply-pipe is provided with an inlet valve orgate 1), which may be operated by a rod b extending upwardly withinconvenient reach at the top of the tank. In the present instance thevalve 1) is shown as having a vertical sliding engagement in a slit inthe pipe 1), near the end which projects into the chamber A. The tub Bis provided with a discharge-pipe b provided with a valve or cook 12 toregulate the discharge.

The floor D of the washer is semicircular in form and consists ofwoven-wire fabric held in position by means of a suitable frameworkconsisting of longitudinal ribs (Z and end supports (Z, the ribs d andthe end supports d being united at or near the ends of the tub by meansof cross girders d and standards or braces (1 It is intended that thelowermost point of the curved floor D shall be a short distance abovethe bottom of the tub, so as to leave a free circulation of water.

The agitator consists of a hub or shaft E, provided at its ends withjournals e, adapted to rest in suitable hearings in the sides of thetub. At the ends of the hub or shaft E and in proximity to the ends ofthe curved floor of the Washer depending arms 6 are located, fixed atone end to the shaft E and having fixed to their opposite endsoppositely-diverging paddles or wings Q The depending arms e are furtherunited by a strengthening brace or girder 8 Upon opposite sides of thearms 6', at each end of the hub or shaft E, yielding arms 6 are located,the said arms being pivotally secured to the hub or shaft E, in thepresent instance to disks a fixed on the shaft, the lower ends of thesaid arms 6 being provided with wings or paddles e", set at aninclination to the arms, the direction of the inclination being awayfrom the central arm or arms 6. The two corresponding arms 8 at oppositeends of the washer upon each side of the central arms 8 are preferablyconnected by braces or girders e", and the said arms are held normallyaway from the central arms 6 by means of springs F, inserted between thearm e and the arms a. It is intended that the arms e and 9 shall be ofsuch length as to bring the lower edges of the wings or paddles e and enear the inner surface of the curved floor of the washer. The agitatormay be rocked back and forth within the tub, with its Wings or paddlesin proximity to the curved floor D, by means of a crank G, fixed to theshaft E.

The height of the water within the tub is determined by means ofsuitable overflowopenings If.

The operation is as follows: Before admitting the water to the tub itstemperature is carefully ascertained in the supply-tank A, and suchtemperature may be raised or lowered by the admission to the supply-tankof steam or hot'water and cold Water through suitable supply-pipes. (Notshown.) When that temperature of" the water has been obtained which isas high as the filtering material will safely stand without danger ofbecoming injured, the gate o may be opened and the water admitted to thetub and to the filtering material held suspended therein upon the curvedfloor D. The rocking of the agitator back and forth within the tub will,because of the inclination of the wings or paddles in oppositedirections from the center, tend to lift the filtering material uptoward the top of the tub as the agitator is swung in that direction,while the paddle upon the descending side of the agitator will ridesmoothly over or through the filtering material, allowing the same toaccumulate upon the upper or outer side of it. When the agitator ismoved in the opposite direction, it will tend to lift the material uponthat side toward which it is rocking, and the side which before liftedwill in turn ride over or through the material without seriously chafingor stirring it. A constant and thorough rinsing of the material is thusobtained. In addition to this, the yielding support of the arms upon theopposite sides of the center will cause the load lifted by the arms a toexert back-pressure against the tension of the springs F, and therebysqueeze the material which shall be left between the paddle upon the arm6 and that upon the central arm 6'. A squeezing and rinsingrof thematerial are thus efiected without seriously stirring or chafing thematerial, and the cleansing operation is rapid and complete. 7 W

What I claim is,

1. The combination, with a tub having a curved open-work support for thefiltering material and means for admitting water to the tub, of avibratory agitator provided with an arm having a yieldingimotion towardthe central portion of the bottom against the tension of a spring, andan outwardly-slanting paddle on the yielding arm adapted to travel inproximity to the curved support, whereby the material is gently liftedasthe paddle is swung toward the outer edge of the bottom and the paddleallowed to ride smoothly over the material as it is swungin theoppositedirection, substantially as set forth.

2. The combination, with a tub and a supply-tank having a valvedcommunication therewith, of a curved open-Work bottom within the tub forholding the filtering material, an agitator having a vibratory movementwithin the tub, the said agitator being provided with rigid armsandpivoted swinging arms, paddles at their free ends, said paddles springsinterposed between the rigid and swinging arms, substantially as setforth.v
